# leetcode 分类专题刷刷刷
这个仓库原来是我私人的刷题库，本来是有解答和一些学习链接的，后来断了一段时间，现在重新捡起。
现在根据 [ssh](https://github.com/sl1673495) 大佬的 [leetcode-javascript](https://github.com/sl1673495/leetcode-javascript) 仓库把每个分类下的每个推荐题都刷一下，加强一下自己的算法基础。但是这个仓库有点不好就是，按照 README 的分类顺序去刷是对新手有难度的，所以我会在下面给出正确的刷题顺序，大家只要按着这个顺序走就可以。
另外，我会把每个分类在 leetcode 建好对应的公共可访问的收藏夹，大家点击每个下面每个标题旁边的 ⭐️ 就可以打开收藏夹地址。
